About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG791652971 or 791652971. Listed at 25 retailers as of November 1, 2026, with prices from $347 to $2,975, a $2,628 spread on the same certified stone. Do Amore Diamonds lists it at $2,975. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
